v- AUTOMATIC TRAP FOR WASH-BASINS.

SPECIFICATION 'forming part of Letters Patent No. 326,277, dated September 15, 1885.

Application tiled August 15, 1884.

To all whom t may concern.:

Be it known that we, WILLIAM E. DELE- HANTY, of the city and county of Albany, in the State of New York, and EDWARD J. MUR- PHY, of Greenbush, in the county of'Rensselaer and State of New York, have invented certain new and useful Improvements in Au tomatic Traps for Wash-Basins, &c., of which the following is a specification.

Our invention relates to improvements in automatic traps for the waste-water pipes of wash-basins and other similar apparatus; and

theobjects of our invention are to provide suitable selfoperating devices for preventing the iniiow of noxious gases through the wastewater pipe, and to utilize the weight of the Waste water, in combination with its floating properties, for automatically operating the valve of the trap. These objects we attain by means of the mechanism illustrated in the accompanying drawings, which, being herein referred to, form part of this specification, and in which- Figure l is a vertical section of our invention as applied to a wash-basin; Fig. 2, a detached vertical section of part of the trapchamber, showing the trap-valve open; Fig. 8, an enlarged plan view of rosette for the valve-rod; and Fig. 4, an enlarged vertical section of same, showing the manner of locking the valve-rod in its raised position.

As represented in the drawings, A is a wash-basin of the usual and well-known form,

. and B the slab which forms the top of the casing; C, the trap-chamber; D, trap-valve5 E, waste-water pipe from basin to trap-chamber; F, branch pipe from cap of trap-chamber to oat chamber; G, iioat chamber; H, float; I, valve-rod, and J handle of valve-rod.

The trap chamber C is a separate vessel, preferably made of glass, and provided with a detachable metallic cover, C', which has a transverse passage, c, across its upper face, and a pendent pipe, c', attached to or formed upon its lower face, so as to form a continu- 'ous communication with the transverse passage c.

An outlet-pipe, c?, is connected to one side of the chamber C, near its upper end, and is connected by means of a suitable waste-water pipe to the drainage system of the building (No model.) A

wherein this device is used. The ou-tlet-pipe c2 is provided on its inner end with a hood, c3, which projects downward inside of the chamber C to a point below the water-line of said chamber.

The waste-pipe E is connected to the transverse passage c,-so as to deliver the water from the basin A directly into said passage.

` The branchpipe F is connected to extend vertically from one end of the transverse passage c to the under side of the :float chamber G, whichlatter is secured to the under side of the slab B at a point that is conveniently adjacent to the basin A.

The branch pipe F is provided with a slipjoint which works in a stufingbox,.f, for the purposeof adjusting the apparatus to different heights of wash-stands. d

The iloat H is tted to reciprocate freely in a vertical direction in the tloat-chamber G, and is provided with a pendent sleeve, h, through which the valveopcrating rod I passes freely, but said rod has no fixed connection to the float H.

The valve operating rod I is preferably made of a tube which is arranged inside of the branch pipe F, and is connected by means of an adjustable joint to the extension-piece i', which passes freely through a conical seat, c, secured to or formed on the cover O of the trapchamber. Said extension-piece is provided with a valve, i', which fits upon the seat c4, so, as to form a water and gas tight joint at that point when the valve-operating rod is pushed down to its lowest point of movement to close 'the trap-valve D; and, as will be seen in Fig. 1, when said trap-valve is closed against the end of the pipe c, the valve i will also be closed down upon its seat c4, so as to effectually close the latter point against any leakage of the water from the pipe F, and prevent the escape of any sewer-gas through the opening through the seat c4. trap-chamber O the extension-piece z' is pivoted to the outer end of the lever d, which is hereinafter fully described. The upper end of the rod I is provided with a socket, i2, having at its lower end projecting arms, or a flange, i3, against which the float H as it rises will engage to move said rodin an upward direction. The downward movement of said Within the IOO lifted by means of said handle.

rod is facilitated by means of a weight, fi, which is attached to said rod.

The handle .I is attached to the socket i2 by means of a stem, j, provided with a iiange,j, which engages with 4the upper end of said socket in such mannerrthat the rod I can be lifted by the float H without raising the handle J; or, when required, said rodmay be The handle J is provided with wingsj?, which are adapted to slide in the notches k of a rosette, K, that is secured to the upper side of the slab B. The wings j2 are so arranged that, when the handle J is raised and turned a partial revolution, said wings will rest on the top of the rosette K and retain the rod I in its raised position.

rIhe valve D is composed of a hollow indiarubber ball, that is iitted to move upwardly and seat against the lower end ofthe pendent pipe c', and to form a tight joint therewith. Said valveis disconnected from any operating mechanism, so as to be free, when relieved from a superimposed pressure, to be floated upward in the water, which will always lie in the trap-chamber G, and thereby eiiect the closing ofthe opening through the pendent pipe c, whether the valve-operating rod I is in position to effect the closing" of the valve or not. Guides d/ are formed on the lower end of the pendent pipe c, for the purpose of guiding the valve D and preventing its displacement. rlhe lever d is i'ulcrume'd to one ofthe guides d. The outer end of said lever is pivoted to the extensionpiece i, and itsinner end is pivoted to a cup, di, which bears against the inner side of the ball-valve D.

The automatic operation of our apparatus is as follows: The basin A being filled or par: tially tilled with water, on the removal of the stopper from the outlet of said basin the water will pass down through the wastepipe E and up through the branch pipe F into the tioatchamber G. Vhen sut'iicicnt water is collected in said chamber, the float H will rise, and thereby the rod I will be lifted to relieve the valve D from the pressure of said rod and the weight i", which pressure (through the intervention of the lever d) tends to force said valve upward in close contact with the seat. As soon as the valve D is so relieved the weight of the superincumbent water acting on the valve forces it from its seat and permits the water to pass out through the trapchamber G and ontlet-pipe et until an equilibrium is established to permit the rod I to fall and effect the return ot' the valve D to its seat. Vhen required7 the handle J can be held in the raised position, as hereinbefore described, and shown in Fig. 4, thereby relieving the valve from the upward pressure due to the rod I and weight i* when in the last-named condition. Whenever the weight of water bearing upon the upper side of the valve is sufficient to overcome the floating power ofthe water below the valve, the latter will be forced from its seat to permit the water to escape, as above described, until the oating power of the water in the chamber C exceeds the pressure acting upon the upper side of the valve D, whereupon the latter will be automatically restored to its seat.

It will be seen that all outlets for the escape of gases from the sewers are effectively sealed by the upward seating of the valve D and the downward seating of the valve i. By the upward sealing of the valve D we remedy a well-known defect in traps in which the sealing is effected by a downward movement of the valve, which defect consists in the liability ofthe valve to be raised by a sudden influx of gas or a back-pressure in asystein of connected waste-pipes, wherein the waste water from an upper .Story is apt to back up and raise an upward-opening valve from its seat.
